The maximum number of electrons in a $p$-orbital with $n=5, m=1$ is$-$

The magnetic quantum number for an electron when the value of principal quantum number is $2$ can have ............ values.

An electron is in one of the $3d$ orbitals. Give the possible values of $n$,$l$,and $m$ for this electron.

In the ground state of $Cr$,the number of electrons with $l = 1$ and $l = 2$ in its electronic configuration are respectively:

The number of electrons with $(n+\ell)$ values equal to $3, 4$ and $5$ in an element with atomic number $(Z) = 24$ are respectively $(n =$ principal quantum number and $\ell =$ azimuthal quantum number).

The difference between the orbital angular momentum of an electron in a $4f$ orbital and another electron in a $4s$ orbital is
